Over 650 investigative cases affected by DNA analyst’s data manipulation

652 cases between 2008 and 2023 are affected. 

Cases before that are still under review.

 A former DNA analyst with the Colorado Bureau of Investigation (CBI) manipulated DNA results and “cut corners” – and as a result, all of her work at the agency over nearly 30 years has been called into question.

Those findings emerged from an internal affairs investigation that commenced in September and pertained to Yvonne “Missy” Woods, a devoted employee who has served the CBI faithfully for 29 years. This announcement was made by the agency on Friday.

The Weld County Sheriff’s Office fired a DNA analyst, who worked at a local lab for over 10 years, after an investigation found “anomalies” in her work. FOX31’s Talya Cunningham hears from a legal expert about what this could mean for the cases involved.

Nucleix, a Tel-Aviv-based life sciences company, was able to create credible DNA evidence that could be used to finger the wrong person, proof that even genetic evidence can be manipulated (beyond planting a hair or used cigarette) just like other physical traces. “You can just engineer a crime scene,”

Attorney Michael Komorn believes a recent policy change in the way Michigan State Police forensic science crime labs report marijuana may have led to years of wrongful convictions.

More than 3,000 cases may have been impacted by inaccuracy of MSP’s marijuana testing

(WXYZ) — The Michigan State Police say more than three thousand cases involving alleged marijuana impairment could have been false positives. Last week, the MSP Forensic Science Division announced they were halting all testing of marijuana drug samples due to the possibility that the tests were positive for CBD, rather than just THC. The state police warned prosecutors not to rely on the THC toxicology results until they could learn more about the alleged problems in the testing.
